Argh! This is quite correct. As previously mentioned, I am in an area where 3G frequency is not compatible with Jolla radio hardware, but 2G and LTE signal is.

I just made a call, which took a while to connect, and this time while I was on the call I looked at the network status icon, and it said '2G'.

So the switch from LTE to 2G when making a call is now automatic, but they still cannot co-exist, and I suppose I cannot receive phone calls still unless the phone is still in 2G. That's why I thought I could receive calls properly earlier. Bah.

Is this is a problem with the LTE vs. 2G spec, or could something perhaps be done in software? (i.e. be online in 2G as well as LTE) I realise it would probably cause battery drain.

Edit: I submitted this to Jolla: https://together.jolla.com/question/...ot-accessible/.
